Diet soda may benefit the waistline, but a new study suggests that people who drink it every day have a heightened risk of heart attack and stroke.
The study, which followed almost 2,600 older adults for a decade, found that those who drank diet soda every day were 44 percent more likely than non-drinkers to suffer a heart attack or stroke.
The findings, reported in the Journal of General Internal Medicine, don't prove that the sugar-free drinks are actually to blame.
There may be other things about diet-soda lovers that explain the connection, researchers say.
"What we saw was an association," said lead researcher Hannah Gardener, of the University of Miami Miller School of Medicine. "These people may tend to have more unhealthy habits."
